Here a list of points that could be important when selecting an ISP:

Dial-up modems typically have a maximum theoretical speed of 56 kbit/s (using the V.92 protocol), although in most cases only up to 53 kbit/s is possible due to overhead and FCC regulation. These speeds are the maximum possible; in almost all cases transfer speeds will be lower, averaging about 32 kbit/s. Other factors such as line noise further reduce achieved transfer rates. Dial-up connections usually have high latency that can be as high as 200 ms or even more, which can make online gaming or videoconferencing near impossible. Some games, such as Star Wars: Galaxies and The Sims Online are capable of running on 56 K dial-up. Gamers with dial-up connections are often disconnected from game servers due to the "lag", or high latency, of the connection.
If you are a gamer, we obviously recommend broadband.

Dial-up access is an inexpensive, slower form of Internet access in which uses a modem connected to the computer and a telephone line to dial a Internet service provider's (ISP) node to establish a modem-to-modem link, which is then routed to the Internet. It is currently regarded. by many. as legacy technology given the advent of widely available
